Patented May 19, 1931 UNITED STATES PATENT. OFFICE WILLIAM B. WOOD'WABD,OF WASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR TO JOSEPH SHAPIRO, OFBALTIMORE, MARYLAND BLADE SHABPENER Application filed July 9, 1928.

An object of this invention is to provide a cheap, simple and convenientdevice for sharpening razor blades.

A. further object of my invention is to provide a device which is simplein construction, made of few parts which lend themselves readily tomultiple production and can be cheaply produced.

With the foregoing, and other objects in view, the invention consists ofa novel construction, hereinafter more specifically illustrated in theaccompanying drawings, where are shown improvements; but it is to beunderstood that changes, variations and modifications may be resorted towithout departing from the scope of the impending claims.

In describing the invention in detail, reference is had to theaccompanying drawings which form part of the invention, and wherein likecharacters of reference indicate corresponding parts throughout theseveral views,

in which- Figure 1 is a perspective view of my improved sharpener;

Figure 2 is a perspective view of the same of a flat rectangularmetallic box 10, consisting of a top 11 and a bottom 12. The top andbottom members are stamped from any suitable material, and are hingedlyconnected at 13, so that they may be readily separated for Formedintegral with the top and bottom members are inwardly bent portions 15,which serve as sharpening elements.

These inwardly bent portions 15 are so constructed that they slanttowards the center of the top and bottom members. The top and bottommembers, after having the sharpening elements formed therein, are casehardened so as to properly serve as sharpening memhere. Through the topmember 11 is cut an Serial No. 291,357.

elongated opening 17 in which is placed reciprocating member 19, whichextends to the outside of the container to form a handle 20, and extendsinto the container to form a blade carrier 21. Blade carrier isprevented from becoming dislodged by the elongated opening by lugs '22,or any other suitable means.

After a blade has been placed upon the blade carrier, the top and bottommembers are secured together by fastening means 23 and the blade is thencaused to move to and fro against the sharpening elements.

What I claim is:

1. A blade sharpener comprising a shallow box like container, sharpeningelements formed on the longitudinal edges of the top and bottom of thebox, said sharpening elements inclined toward the central portion ofsaid top and bottom members of said box, there being an elongatedopening in the top of said box, a reciprocating blade carrier slidablysecured in said elongated opening, said carrier having means extendingthrough said elongated opening for moving said blade carrier to and fro.

2. In a device of the class described, two rectangular sheets ofmaterial, a series of sharpening elements formed integral with saidsheets of material, the edges of said sheets of material turneddownwardly forming shallow containers, said shallow containers hingedlyconnected at one edge, there being an elongated opening in one of saidshallow containers, a blade carrier slidably secured in said elongatedopening.

3. In a blade sharpener, a box like container for entirely inclosing ablade while being sharpened, sharpening elements formed integral withthe top and bottom of said container, and means for moving a bladeacross said sharpening elements, said means com prising a length ofmetal bent upon itself at the mid portion to form a handle projectingthrough an elongated opening in the top of the container and the ends ofsaid strip of metal bent to form a U. shaped member. 4. In a bladeshapener, comprising a metallie box, having an elongated opening ,in itstop, a plurality of spaced apart inwardly projecting sharpening members,said sharpening elements forming a part of the top and bottom of saidbox, a. reciprocating blade carrier slidably secured in said elongatedopening, said carrier having a portion thereof extending through theelongated opening to form a handle for the blade carrier. 7 4
